The second pre-season test of F1 2012 gets underway at Barcelona on Tuesday morning with Mercedes taking centre stage as it launches its MGP W03 – the car it hopes can move it closer to the dominant Red Bull squad – most of the rest adding to the mileage they achieved at Jerez, and Marussia and HRT yet to show off their new machines.
